Vaccination is the administration of vaccine or antigenic material to help the immune system to develop adaptive immunity to a pathogen. They have been used to combat or even eradicate many deadly diseases. Apart from traditional vaccines, researchers have come out with therapeutic vaccines that treat you after you have contracted the illness.
Generally, a neonatologist or a child specialist administers vaccine to children. You can get vaccinated at a hospital or a health center. Many immunizations are given in shots. The child may experience brief pain or discomfort. Vaccination introduces pathogen inside the body, so that the immune system is triggered and the body prepares itself to fight infections. Similarly, Inoculation introduces a living organism in a controlled way to minimize the risk of infection. It is an older method of fighting the same disease as being injected with live smallpox serum taken from a patient who has had smallpox.
Vaccination in general terms imitates a particular pathogen and trick the body to produce the requisite antibodies to develop resistance towards infection caused by thee pathogens.
One such vaccine is the influenza vaccine also known as flu shot is the vaccine that protects against influenza. Since the influenza virus changes rapidly, a new version of this vaccine is developed twice a year. Flu vaccines develop antibodies about two weeks after vaccination. These antibodies provide immunization against infection. Traditional flu vaccine called trivalent are made to protect against three flu viruses-
An influenza A (H1N1) virus
An influenza A (H3N2) virus
An influenza B virus.
Quadrivalent vaccine is made to protect against four flu viruses.
The injectable influenza virus is recommended as against nasal spray flu virus.

Standard dose trivalent shots
